Hyperledger is an open source project, initiated by the Linux Foundation in 2015, to advance blockchain digital technology and transaction authentication. Hyperledger aims to promote cross-industry collaboration to build an open platform that can meet the requirements for multiple domains and simplify business processes. All nodes in a Hyperledger network forge a peer-to-peer distributed ledger, and the overall distributed ledger is totally shared and decentralized. Its information is jointly updated using a consensus mechanism. Hence, it is well suited for financial applications and many other industries, such as manufacturing, banking, insurance, and the internet of things. By creating a distributed ledger open standard and implementing virtual and digitized value exchange (e.g., asset contracts and energy transactions), it is possible to track and conduct transaction securely, efficiently, and cost effectively.

CDH’s Cloudera Manager provides fine-grained visualization and control of every component in CDH, including HDFS, YARN, HBase, Hive, and Impala, which helps set an enterprise-level deployment standard. Leveraging Cloudera Manager, operations personnel can improve their cluster’s performance and service quality while lowering management costs. The design goal of Cloudera Manager is to make management of an enterprise’s data center easy and intuitive. This software can automate the installation procedure, decreasing the time to cluster deployment. Cloudera Manager has a real-time and runtime status panel for all nodes within a cluster and a central control console by which users can configure a cluster. In addition, Cloudera Manager includes a set of report and debug tools that can help users optimize performance and increase utilization rate of clusters.

Shouzhuang Jiang and 丛宏雷 discuss Hyperledger’s integration with CDH’s big data ecosystem and its real-world applications. Cloudera Manager can easily add new components into CDH’s big data platform, so it is possible to use Cloudera Manager to deploy Hyperledger into an enterprise-level big data environment and integrate data flow with efficient analysis—that is, use your existing big data platform to store and analyze data generated by Hyperledger.

Membership services that manage identification, privacy, and confidentiality on the network. Participants register to obtain identities, which enables the attribute authority to issue security keys for transacting. By using the blockchain to record the update history of a ledger, auditors can view transactions pertaining to a participant, assuming that each auditor has been granted proper access authority by the participants.

Chaincode services, a secured and lightweight way to sandbox the chaincode execution on validating nodes. The environment is a “locked down” and secured container with a set of signed base images that contain secure OS and chaincode language, runtime, and SDK images for Golang, Java, etc.

How Wanda Internet Technology Group applies Hyperledger in its Digital Right Exchange Platform to ensure all transaction history remains confidential and cannot be tampered with. Applying Hyperledger in a supply chain management system and leveraging its tracking capacity can link producing and sales parties, creating a brand-new sale model.
